Answer:

B = 48°

b = 29.7

c = 39.1

Step-by-step explanation:

You have made a Mistake which is C = 102° Not 120°

So, Lets begin with the Problem

Since the Sum of Interior Angles of the Triangle = 180 °

Then A+B+C=180

Then 30+B+102=180

Then  B+132=180

Subtract 132 from Both sides

B = 180 - 132 = 48°

Applying Law of Sines

[tex]\frac{a}{sinA} =\frac{b}{sinB}=\frac{c}{sinC}[/tex]

by substituting

[tex]\frac{20}{sin30} =\frac{b}{sin48}=\frac{c}{sin102}[/tex]

Then   [tex]b=\frac{20sin48}{sin30} =29.7[/tex]

Then   [tex]c=\frac{20sin102}{sin30} =39.1[/tex]

Using proportions, it is found that about 175 trees are oak.

A proportion is a fraction of a total amount.

For the four samples, the proportions are: {0.3, 0.15, 0.26, 0.29}.

Hence, the mean proportion is given by:

M = (0.3 + 0.15 + 0.26 + 0.29)/4 = 0.25

Out of 700 trees:

700 x 0.25 = 175.

Answer:

x=4

Step-by-step explanation:

both angles add up to 90* because it is a right angle

10x + 12x + 2 = 90

22x + 2 = 90

subtract 2 from both sides of the equation

22x = 88

divide both sides by 22

x = 4

Answer:

Step-by-step explanation:

The yards of silk bought is  1.49 yards and the yard of cotton bought is 2.76 yards.

The two equations are known as simultaneous equation. They would be solved using elimination method.

x + y  = 4.25 equation 1

16.90x + 4y = 36.25 equation 2

where:

x = yards of silk bought

y = yards of cotton bought

In order to determine the value of x, multiply equation 1 by 4.

4x + 4y = 17 equation 3

Subtract equation 3 from 2

19.25 = 12.90x

Divide both sides of the equation by 12.90

x = 1.49 yards

In order to determine the value of y, substitute for x in equation 1

1.49 + y = 4.25

y = 4.25 - 1.49

y = 2.76 yards

Step-by-step explanation:

Using the z-distribution, the 95% confidence interval is (0.1279, 0.1921), and it means that we are 95% sure that the proportion for the entire population is between these two values.

A confidence interval of proportions is given by:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which:

In this problem:

Hence:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.16 - 1.96\sqrt{\frac{0.16(0.84)}{500}} = 0.1279[/tex]

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.16 + 1.96\sqrt{\frac{0.16(0.84)}{500}} = 0.1921[/tex]

The 95% confidence interval for the true proportion of households that have experienced property damage due to crime is (0.1279, 0.1921), and it means that we are 95% sure that the proportion for the entire population is between these two values.

Answer:

y=2x-1

Step-by-step explanation:

Since it is parallel to y=2x-5, they have the same slope of 2.

Now you're going to plug the point and slope into the following equation: y-(y value of point) = slope ×(x-(x value of point))

y-5= 2 (x-3)

Now you simplify:

y-5=2x -6

y=2x-1

Answer:

65°

step-by-step explanation:

solve for x:

116x - 1 = 114x + 1

116x - 114x = 1 + 1

2x = 2

x = 1

Find angle C:

m∠C + 116(1) - 1 = 180°

m∠C = 180° - 115

m∠C = 65°

Solution:

We know that:

This means that:

Step-1: Find the value of x.

[tex]116x - 1 = 114x + 1[/tex]

[tex]\rightarrow 116x - 114x = 1 + 1[/tex]

[tex]\rightarrow 2x = 2[/tex]

[tex]\rightarrow \bold{x = 1}[/tex]

Step-2: Solve for ∠C.

[tex](116x - 1) + (114x + 1) + \angle C + \angle C = 360\°[/tex]

[tex]\rightarrow (116x - 1) + (114x + 1) + \angle C + \angle E = 360\°[/tex]                           [∠C = ∠E]

[tex]\rightarrow 116x - 1 + 114x + 1 + 2\angle C = 360\°[/tex]                                  

[tex]\rightarrow 230x + 2\angle C = 360\°[/tex]                                        

[tex]\rightarrow 230(1) + 2\angle C = 360\°[/tex]                                                                 [x = 1]

[tex]\rightarrow 230 + 2\angle C = 360\°[/tex]                                                                          

[tex]\rightarrow 2\angle C = 360 - 230[/tex]

[tex]\rightarrow 2\angle C = 130[/tex]

[tex]\rightarrow \boxed{\bold{\angle C = \frac{130}{2} = 65\°}}[/tex]                                                      

The computation of the angle given simply shows that the value of angle x is 109°.

From the information given, it can be noted that two numbers are given and there's a subtraction sign between the numbers given.

Therefore, in this scenario, one simply just has to subtract the numbers. Therefore, thus goes thus:

x = 304 - 115

x = 189

The value of x is 189°.
